Randomized Controlled Trial Multicenter Study
Plasma First in the Field for Postinjury Hemorrhagic Shock.
Hemorrhage is the most preventable cause of death in civilian and military trauma, and despite tremendous advances in patient transport in the field, survival within the first hour has changed little over the past 40 years. The pathogenesis of trauma-induced coagulopathy is multifactorial, but most authorities believe there is an early depletion of clotting factors. ⋯ The rationale includes the possibility that plasma-first resuscitation may be advantageous beyond direct effects on clotting capacity. The study design is based on a ground ambulance system that allows rapid prehospital thawing of frozen plasma.

Pre-Hospital Hypertonic Saline Resuscitation Attenuates the Activation and Promotes Apoptosis of Neutrophils in Patients With Severe Traumatic Brain Injury.
Activation of polymorphonuclear neutrophils (PMNs) is thought to contribute to traumatic brain injury (TBI). Since hypertonic fluids can inhibit PMN activation, we studied whether hypertonic fluid resuscitation can reduce excessive PMN activation in TBI patients. ⋯ This study demonstrates that prehospital resuscitation with HS can partially restore normal PMN activity and the apoptotic behavior of PMNs, whereas resuscitation with HSD was largely ineffective. Although the results are intriguing, additional research will be required to translate these effects of HS into treatment strategies that improve clinical outcome in TBI patients.

Shock State: An Unrecognized and Underestimated Presentation of Drug Reaction with Eosinophilia and Systemic Symptoms.
Some patients with drug reaction with eosinophilia and systemic symptoms (DRESS) are probably admitted in intensive care unit (ICU), but data concerning their clinical features at admission are scarce. Therefore, in the present study, we used a clinical network of French intensivists to study the clinical features and evolution of DRESS patients hospitalized in ICU. A national, retrospective, multicenter study collected DRESS cases hospitalized in ICU for DRESS from 2000 to end of 2011. ⋯ Initial bacteriology was negative in all patients. Human herpesvirus reactivations were found in five of 15 cases. In conclusion, shock without bacteriological documentation associated with multiple organ failure is the most common presentation of DRESS at admission in ICU and is associated with a higher mortality than previously described.

Prospective comparison of three risk score models at three different surgical intensive care units.
Although risk score models are of great value, their use is restricted because of the additional effort involved. The aim of this study was to compare three different score systems. Each of these requires a different degree of effort by the medical staff. One of the score systems is solely based on routine laboratory parameters. Data were collected on three different ICUs units, with each showing a large variety in patients' health conditions. ⋯ The results of this first multicenter study comparing three risk score systems indicate that it is possible to establish a general risk score for surgical intensive care patients on admission date. Such a risk score is solely based on quality-controlled, low-cost routine laboratory parameters.

The objective of this study was to investigate the association of endothelial-related markers with organ dysfunction and in-hospital mortality to validate our earlier findings in a multicenter study. We hypothesize that (i) endothelial biomarkers will be associated with organ dysfunction and mortality in sepsis and that (ii) soluble fms-like tyrosine kinase 1 (sFlt-1) holds promise as a novel prognostic marker in sepsis. ⋯ This multicenter validation study confirms that markers of endothelial activation are associated with sepsis severity, organ dysfunction, and mortality in sepsis. This supports the hypothesis that the endothelium plays a central role in the pathophysiology of sepsis and may serve as a more accurate prediction tool and a target for therapies aimed at ameliorating endothelial cell dysfunction. In addition, sFLT-1 holds promise as a novel sepsis severity biomarker.
